Dog booties with suspenders for giant breeds?

My dog is over 50 percent Mastiff breeds. He'll be 9 in March. He absolutely loves being outside when it snows, but his paws start hurting because of the cold so much so that he can barely walk. He doesn't like his paws messed with. I have looked and looked for suspenders booties for his size, but I keep coming up empty. He is also catching the tops of his paws on raised areas and slips a lot on slick areas. Does anyone happen to have recommendations??
